SlNKER-BAR FOR STRAIGHT-KNITTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 403,985, dated May 28,1889.

Application led September 17, 1888. Serial No. 285,562. (No model.)

To a/ZZ whom t may concern:

Beit known that I, FRANK. E. BUsIEL, of Laconia, in the county ofBelknap and State of New Hampshire, have invented a new and usefulImprovement in Sinker-Bars for Straight-Knitting Machines, of which thefollowing, taken in connection with the accompanying drawings, is aspeciiication.

The object of my present invention is to secure the sinkers ofastraight-way knittingmachine rmly in xed positions without the use ofsolder or other permanent fastening, so that when a sinker becomes wornor broken it may readily be removed and replaced by a new one, and thisis accomplished by a novel device which will be more readily understoodby reference to the description of the drawings and tothe claim to behereinafter given.

Of the drawings, Figure l represents a front elevation of a portion of asinker-bar having a series of sinkers secured therein according to myinvention. Fig. 2 represents Fig. 3 represents a sectional elevation ofthe same, the cutting-plane being on line o@ on Fig. l; and Fig. 4:represents an elevation of a sinker.

In the drawings, Aisa sinker-bar, the front side ofwhich is providedwith a series of vertical grooves, a a, in which are mounted the sinkersb b. The front side of said sinker-bar A is also provided with adovetailed groove extending the entire length thereof and of such adepth as to extend beyond the front edges of said sinkers b b, each ofwhich is provided with a dovetailed notch, c, as shown in Fig. 4, sothat when the locking-bar B is inserted into said dovetailed groove itwill enter the notches o c in the sinkers h b and secure them irmly inposition, so that they m ay not be moved either endwise or in thedirection of their widths.

Bars have heretofore been in use which engage with notches in the edgesof the sinkers, but said bars have been arranged in bearings independentof the sinker-bar and movable vertically to adjust the sinkers, or havebeen provided with a cam-groove and were reciprocated in their bearingsto successively move the sinkers vertically, and in either case said barwould vnot of itself prevent the transverse movement of the sinkers; butin my improved device, by virtue of the dovetailed longitudinal grooveformed in the sinker-bar, the locking-bar B prevents either an endwiseor a transverse movement of said sinkers and secures them in fixedpositions without the aid of additional fastenings.

It is obvious that by withdrawing or partially withdrawing the bar Bfrom the groove in which it is mounted any or all of said sinkers may beremoved and replaced by new ones whenever it becomes necessary to do so.

What I claim as new, and desire to secure by Letters Patent of theUnited Stat-es, is-

In a knitting-machine, the combination of a sinker-bar provided withaseries of vertical grooves and a longitudinal dovetailed groove cut inits front side, with a series of sinkers mounted in said verticalgrooves and provided each with a dovetailed notch in its front edge, anda dovetailed locking-bar Iitted to and movable endwise in thelongitudinal groove of said sinker-bar and in the notches in saidsinkers to rmly hold them in position and prevent any movement eudwiseor transversely thereof.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRANK. E. BUSIEL.
